• 02;
• 03;
• 04;
• 06;
• 07;
• 08;
• 09;
• 11;
• 12) in the transport direction (T) of the sheets, wherein the sheets to be shingled are transported from the first processing station (01;
• 02;
• 03;
• 04;
• 06;
• 07;
• 08;
• 09;
• 11;
• 12) to the transfer unit, in a transport plane (29) and lying individually in succession, and wherein the trailing edge in the transport direction (T) of each of the sheets coming from the first processing station (01;
• 02;
• 03;
• 04;
• 06;
• 07;
• 08;
• 09;
• 11;
• 12) is raised relative to the transport plane (29) solely by means of blown air, and a subsequent sheet is pushed underneath the trailing edge of the sheet preceding it in each case, characterized in that additional blown air is blown from above onto the sheets to be transported to the transfer unit, at an acute angle that is formed with the transport plane (29) and in a direction opposite the transport direction (T) of the sheets, wherein the operating width, directed orthogonally to the transport direction (T) of the sheets, of the blown air acting counter to the force of gravity in the direction of the transport plane (29), and the operating width of the additional blown air directed opposite the transport direction (T) of the sheets are each adjusted based on the width of the sheet, directed orthogonally to the transport direction (T) of the sheets.

• 09;
• 11;
• 12) in the transport direction (T) of the sheets, wherein a transport belt (38) for transporting the sheets to be shingled is provided, wherein the transport belt (38) transports the sheets to be shingled from the first processing station (01;
• 02;
• 03;
• 04;
• 06;
• 07;
• 08;
• 09;
• 11;
• 12) to the transfer unit, in a transport plane (29) and lying individually in succession, wherein nozzles for emitting blown air are provided, and wherein the nozzles are arranged so as to raise the trailing edge in the transport direction (T) of each of the sheets coming from the first processing station (01;
• 02;
• 03;
• 04;
• 06;
• 07;
• 08;
• 09;
• 11;
• 12) relative to the transport plane (29), solely by means of the blown air, and so as to push a subsequent sheet underneath the trailing edge of the sheet preceding it in each case, characterized in that a guide surface in which additional nozzles are located is provided, wherein these additional nozzles blow additional blown air, at an acute angle formed with the transport plane (29) and opposite the transport direction (T) of the sheets, from above onto the sheets to be transported to the transfer unit, wherein the operating width, directed orthogonally to the transport direction (T) of the sheets, of the blown air acting counter to the force of gravity in the direction of the transport plane (29) and/or the operating width of the additional blown air directed opposite the transport direction (T) of the sheets are each adjusted based on the width of the sheet, directed orthogonally to the transport direction (T) of the sheets.
